Nitsuko Digital System Feature And Terminal Programming Manual

							DP AND DTMF COMPATIBILITY
Description
The system administrator can program each trunk for Dual Tone Multifrequency (DTMF) or Dial Pulse (DP) di-
aling.  This allows the system to connect to any combination of DTMF or DP trunks.
DP/DTMF Compatibility also provides Pulse to Tone Conversion. Pulse to Tone Conversion lets a user change
their extension’s dialing mode while placing a call.  For systems in a DP area, this permits users to access dial-
up OCCs (e.g., MCI or GTE Sprint) from a DP area.  The user can, for example:
•Place a call to an OCC over DP trunks.
•Wait six seconds after dialing the OCC’s local number.
•Dial the OCC security code and desired number.  The system dials the digits after the six-second wait as
DTMF.
Conditions 
None
Default Configuration
•All trunks have loop start DTMF signaling.
•Since all COSs have Toll Restriction Level 0, all COSs allow Pulse to Tone Conversion.  Continued dial-
ing is always allowed by COS 0.  Continued Dialing is switchable (by Toll Level) for all other COSs.
Programming
Required Programming
➣E- Trunks, E2- Trunk Circuit Type
Assign a circuit type that matches the signaling for each connected trunk.  If a trunk has both DP and
DTMF signaling, program it for DTMF. (see page 342)
Other Programming
➣AP- Allow Active Dial Pad
Enable for each Toll Restriction level that should allow Pulse to Tone Conversion. [Y=allow, N=deny]
➣CP- Extension Toll Restriction Level (BY1:0-2)
Assign a Toll restriction level to each COS. [0-7]
➣E- Extensions, E3- Extension Class of Service
Assign a COS to each extension. [00-27, 30 for operators]
Related Features
Special Services and OCC Compatibility
After a special service answers, it requires DTMF signaling. Pulse to Tone Conversion lets a user dial a
special service from a DP area.
Speed Dial
If a Speed Dial number uses a DP trunk and contains a pause, Pulse to Tone Conversion can be automat-
ic.  The digits before the pause dial out DP.  The digits after the pause dial out DTMF.
Feature Operation
To Convert your dialing from pulse to tone:
Your outside call must initially use pulse signaling.
1. Place initial call.
2. Wait six seconds.
3. Dial additional digits.
These digits dial as DTMF.

							DIGITAL DOOR BOX
Description
Available in Software Levels:
BaseAUX

Y5.0
> 
Y2.0
The Digital Door Box (P/N 88545) is a self-contained Intercom unit typically used to monitor an entrance door.
A visitor at the door can press the Door Box call button (like a door bell). The Door Box then sends chime tones
to all extensions programmed to receive chimes.  To answer the chime, the called extension user just lifts the
handset.  This lets the extension user talk to the visitor at the Door Box.  The Door Box is convenient to have at
a delivery entrance, for example.  It is not necessary to have company personal monitor the delivery entrance;
they just answer the Door Box chimes instead. 
The system can have up to four Door Boxes, installed at extensions 310, 311, 322 and 323.  Each Door Box has
a distinctive chime pattern as follows:
ExtensionChime Pattern

1 The chimes for extensions 322 and 323 are twice as fast as the chimes for 310
 and 311. 
The Relay Box provides relay contacts for up to four Door Box locations.  A relay typically enables an electric
strike on an entrance door next to a Door Box.  After answering the Door Box chimes, the extension user can
press a dial pad key to enable the associated relay.  The visitor at the door can then enter without having an em-
ployee open the entrance for them.  The Relay Box should be installed at extension 309.  The Relay Box has a
normally open (NO) and normally closed (NC) contact for each Door Box.  Refer to Relay Box Installation In-
structions (P/N N1853REL04) for installation information.
Conditions 
(A.) The Door Box is a weather-tight unit, with an operating temperature range of -20yC to 60yC (-4yF to
140yF).  It is not intended for outdoor installation.
(B.) Ringing and Paging affect the way a Door Box alerts an extension:
-
-Incoming ringing stops the chimes (if sounding) or prevents the 
chimes (if ringing occurs before the chimes sound).
Paging turns off an active chime. Conversely, an incoming chime turns 
off a Page announcement in progress.
Default Configuration
No Door Boxes installed.

							DIRECT INWARD LINE (DIL)
Description
A Direct Inward Line (DIL) is a trunk that directly rings an extension, ACD group, UCD group or Ring Group.
DILs give the system administrator additional routing options for incoming calls.
A call will ring the DIL destination.  It follows the programmed number of rings, and if not answered, will con-
vert to key ring.  For example, a Sales Manager can have a DIL for a new sales campaign’s calls.  When a caller
dials the sales campaign number, the call rings the Sales Manager’s phone.  If the Sales Manager does not an-
swer, the call then rings all the other phones with programmed ringing for that trunk.
Conditions 
None
Default Configuration
No DILs programmed.
Programming
Required Programming
➣E- Trunks, E9- Direct Trunk Termination
Assign the DIL destination: extension, ACD/UCD group master number or Ring Group.
➣KS- Programming Keys for Keysets
A DIL to a keyset should ring a key [line #].  If the trunk doesn’t have a line key, it will ring a loop key.
[9=switched loop, 9 and a line group # (0-8)=fixed loop]
Other Programming
➣E- Extensions, ED- Trunk Control, Ring Control
An unanswered DIL diverts to all extensions with ringing for the trunk. Initially, the DIL ignores the ED
programming.  This step is not available to ESL phones.  [R=immediate ring, D=delayed ring, L=lamp
only (no ring), N=night ring]
➣E- Extensions, ED- Trunk Control, Access Control
A user must have access to the trunk to pick up a diverted DIL.  For Private Line type operation, deny ac-
cess to all but the DIL destination. [Y=allow, N=deny]
➣E- Trunks, EI- Night Call Routing
A DIL to an extension in DND routes to the programmed EI night mode destination.
➣NP- Programming Names and Messages
Assign names to DILs.  The name displays after a display telephone user answers the DIL. [16 digits
maximum]
➣QT- System Timers, Camp-On Time
Set how long a DIL Camps-On to a busy ESL set. [0-970 seconds]
➣QT- System Timers, Number of Rings Before Recall
Set how long a DIL Camps-On to a busy keyset. [3-15]

A DIL to an extension in DND routes to the programmed EI night mode destination.
Extension Hunting
A DIL terminated to a UCD master number rings the member that has been idle longest.
A DIL terminated to an extension in a Circular or Terminal Hunt group initiates hunting.
Group Call Pickup
A DIL ringing a Pickup Group member activates Pickup Group coverage for the member extensions.
Group Ring (Ring Groups)
A DIL terminated to a Ring Group rings all members in the group during the day.  The trunk never di-
verts to all extensions with programmed ring and access.  The trunk rings the programmed EI destination
at night.
Line (Trunk) Rotaries (Hybrid Only)
A DIL can be a member of a trunk rotary (for placing calls). While busy on an outgoing call, the DIL is
unavailable for incoming calls.
Night Answer (Off-Hours Ringing)
A DIL ignores ANA (E- Trunks, EI) programming (unless the destination extension is in DND).
Personal Greeting
Outside calls ringing an extension directly (either DILs or via Transfer) hear the Personal Greeting, if en-
abled.  The outside call then rings the specified extension.  If there is no specified extension, the call
rings all extensions with ringing for the trunk.  Outside calls ringing a line key don’t activate Personal
Greeting.
Private Line
A Private Line is a trunk reserved for a single or group of keysets for placing and answering calls.
Tenant Service
You can have unanswered DILs recall to all tenant groups or only to the DIL’s extension tenant group.

							DIRECT INWARD SYSTEM ACCESS (DISA)
Description
DISA permits outside callers to dial a special telephone number and directly access system extensions, trunks
and features. For example, DISA helps sales people who are away from the office but want to use the company’s
trunks for long distance calls.
To use DISA, the outside caller:
•Dials the telephone number that rings a DISA trunk
•Waits for the DISA trunk to automatically answer
•Dials the DISA password (access code)
•Hears system Intercom dial tone
•Can implement many of the system features that use dial pad keys (digits 0-9, # and *)
DISA calls ring system extensions like any other outside call (i.e., on a line or loop key).
The system supports four types of DISA connections:
•DISA Day or Night, DTMF
The trunk receives inbound DISA calls in the day or night mode, and is DTMF when used for
 outgoing calls.
•DISA Day or Night, Dial Pulse (DP)
The trunk receives inbound DISA calls in the day or night mode, and is DP when used for
outgoing calls.
•DISA Night Only, DTMF
The trunk receives inbound DISA calls only at night, and is DTMF when used for
  outgoing calls.  The trunk is a normal DTMF trunk when the system is in the day mode.
•DISA Night Only, Dial Pulse (DP)
The trunk receives inbound DISA calls only when the system is in the night mode,
and is DP when used for outgoing calls.  The trunk is a normal DP trunk when the
system is in the day mode.
DISA trunks must be supervised loop start. 
Conditions 
(A.) The DISA caller must use a 2500 type (DTMF) telephone.  DISA is compatible with calling devices that
meet the DTMF signaling requirements of EIA Specification RS-464.  Additionally, DISA requires sys-
tem DTMF receivers.  The system must have a PCU Module programmed for DTMF decoding (QV-
PCU Circuit Type = 2).
(B.) DISA requires disconnect supervision from telco.
Default Configuration
No DISA trunks programmed.
